I remember that too. There was a line of bikes that had molded plastic pieces that made some look like motorcycles. Some were done really well. They were around for a very short time. My memory isn't sure if there was an exact Battlestar bike. I do kind of recall it, but I imagine someone would have pulled one out when the series was one. I remember the "V-Room" fake plastic motors that kids could add and made the motorcycle sound. i found a better picture of the B.G. Space motorcycle. The whole top piece wouldn't be too hard to make for a real motorcycle. It's tempting, I don't think I cold suffer the humiliation, unless I had a real turbine engine to go with it!
